“Belladonna: in Italian a beautiful lady, in English a deadly poison.” ~ Ambrose Bierce
What are Nightshades?
You may have heard of the term “deadly nightshade” referring to a plant called belladonna, which was used as a poison in ancient times. Lesser known are the commonly eaten vegetables in the same nightshade family. They aren’t deadly, but they contain enough toxins to cause inflammation in some people, particularly those with autoimmune disease. Often, we don’t realize just how much, until we stop eating them:
- Peppers (bell peppers, banana peppers, chili peppers, etc.)
- Red pepper seasonings (paprika, chili powder, cayenne, curry, etc.)
- Goji berries
- Ground cherries
- Ashwagandha (an ayurvedic herb)
- Read labels: terms like “spices” and “natural flavors” often contain the above seasonings, and “starch” often comes from potatoes.
Similar sounding foods that are not nightshades, and are ok to eat:
- Sweet Potatoes
- Peppercorns (black, white and pink)
How Are They Harmful?
First of all, nightshades aren’t harmful to everyone, but they are often harmful to people with autoimmune disease.
These vegetables all look so different, it’s surprising to discover they’re all part of the same Solanaceae family. They all contain toxic compounds called alkaloids. In nature, these protect the plants against insects, by poisoning the insect and dissolving its cell membranes. Unfortunately, alkaloids can have a similar effect in humans, increasing our inflammation, overactivating our immune system, and causing permeability in our intestinal membranes (known as leaky gut), all of which contribute to autoimmune disease. If someone’s healthy, with low inflammation in their body, a balanced immune system, and a healthy and strong digestive tract, they can often eat nightshade vegetables without a problem. However, people with autoimmune disease are vulnerable, and nightshades often exacerbate symptoms.
If you want more details on these compounds and how they affect the body, here are two excellent articles:
What are Symptoms of Nightshade Sensitivity?
- Joint pain
- Stiffness upon waking, or stiffness after sitting for longs periods of time
- Muscle pain and tension
- Muscle tremors
- Sensitivity to weather changes
- Poor healing
- Skin rashes
- Stomach discomfort
- Digestive difficulties
- Mood swings
How Do I Learn If I’m Sensitive?
The only way to know is to eliminate them from your diet for at least 30 days. (No cheating.) Then, reintroduce them into your diet as a test: eat them at least 3 times over a 2-day period, and then stop eating them, and monitor your symptoms for 72 hours. Did you improve during the 30 days? Did you have a negative reaction when you ate them again? If yes, you’re nightshade-sensitive. If no, you’re not.
You’ll find articles on the internet saying there are no peer-reviewed studies to support the nightshade-inflammation connection. This is true, largely because there’s no profit to be made in that research and therefore no funding. But you’ll also find many people who eliminated them from their diet, reintroduced them, and saw a clear connection between eating them and their symptoms. I’m one of those people, as is Sarah from Paleo Mom, Mickey from Autoimmune Paleo, Whitney from Nutrisclerosis, Stacy from Paleo Parents, and many others.
Does the Amount Matter? Can I Eat Just a Little?
I don’t recommend it. When I first went nightshade-free, I gave up the vegetables but kept eating the spices. I thought, ‘How can such a small amount hurt me?’ My inflammation lessened, but some remained. Then I did a strict elimination protocol, avoiding the spices as well. When I reintroduced them 30 days later, I had a huge reaction. Every joint in my body hurt, and it took 2 weeks before I returned to feeling normal again. Elimination diets are powerful learning tools, because by removing a food from your circulation altogether, you eliminate the chronic inflammatory response. When the food is reintroduced, if you’re sensitive, you will get an acute short-term reaction. It’s a very clear communication from your body on what foods are good for you and what foods are not.
Can You Be Sensitive to One and Not the Others?
It’s possible, because each vegetable has a slightly different alkaloid. You can test yourself by reintroducing them one at a time.
How Can I Live Without Them?
Let’s not lie; it ain’t easy. I cried when I learned I had this sensitivity. These are some of the most delicious vegetables and spices. They’re also heavily used in restaurant and store-bought food, making shopping and eating out even more difficult. However, there is a clear reward to a nightshade-free life: you feel better.
We Can Do This! Here are My Survival Tips:
- If you’re craving potatoes, replace them with a starchy alternative: sweet potatoes, beets, parsnips, butternut squash. You can cook all of these the same way you cook potatoes: fries, chips, roasted, mashed, and you know what? They have more flavor, too!
- Although there’s really no substitute for a fresh summer tomato, there IS a substitute for a classic tomato sauce, thanks to Danielle from Against All Grain.
- Nightshade spices usually give food a hot kick. You can still get this sensation through non-nightshade spices: white pepper, black pepper, ginger and horseradish. Usually you’ll need more of these spices than you would of the red peppers. Experiment.
- Restaurants are tricky. Many sauces and spice blends contain nightshade spices. You have two options: ask your waiter how the food is seasoned (and trust them to tell you the truth). Or order your food unseasoned and bring some spices with you. Herbamare is a good choice (lots of flavor, no nightshades).
- If you want to buy lunch meat, unfortunately most of them have nightshade spices. Paprika is especially overused because it adds color. However, I did discover that Boar’s Head and Dietz & Watson both offer an “All Natural Roast Beef” that is nightshade-free, and both brands are common in many grocery stores. Also Whole Foods has a “naked” line of deli meats and rotisserie chickens, which means they are simply meat with nothing (including spice) added.
- US Wellness Meats offers some nightshade-free snack meat options that you can order online. And Epic Bison Bacon Cranberry Bars are delicious nightshade-free jerky.
- There are many websites that offer nightshade-free paleo recipes: My Blog, Autoimmune-Paleo, Clean Plate, Nutrisclerosis, Paleo Mom and Chowstalker. Also, don’t be afraid to modify recipes you already have. You can often remove an ingredient or two without altering the deliciousness of the dish. Get creative and see what substitutions work best for you.
- My final gift to you is a recipe for a nightshade-free curry, which you can use in any of your favorite curry recipes. Put all of these spices in a bowl and stir to blend well, then pour into a spice jar & use as needed:
Nightshade Free Curry
2 Tbsp. ground coriander
2 Tbsp. ground cumin
4 tsp. turmeric
2 tsp. black pepper
1 tsp. dried ginger
1 tsp. dry mustard
